Wild Dormouse Decline and Habitat Welfare

Hazel dormice have declined dramatically in the UK and surviving populations face welfare challenges from habitat fragmentation and climate change.

Key Facts

Dormice have declined by over 70% in the UK over the past 25 years
They are entirely dependent on connected woodland and hedgerow habitat for foraging
Hibernation success depends on adequate autumn body weight gained from hazel nuts and berries
Climate change is causing dormice to emerge prematurely from hibernation risking starvation
Dormouse boxes provide artificial nest sites in suitable habitat

Welfare Considerations

Dormouse welfare is inseparable from habitat connectivity and quality. Fragmented populations cannot access adequate food to sustain hibernation, causing starvation and poor breeding success. Habitat restoration and connectivity are the most impactful welfare and conservation interventions.

What You Can Do

Support People's Trust for Endangered Species dormouse conservation programmes
Manage hedgerows sympathetically to maintain connectivity for dormouse populations
Install dormouse boxes in suitable woodland habitat to support nesting
